EXTENSION-TABLE.

Specification of Letters Patent.

Patented Apr. 27, 1920.

Application fi1ed July 12, 1918. Serial No. 244,553.

To all whom it may concern:

Be it known that I, HARRY CRUMP, a citizen of the Dominion of NewZealand, and residing at 25 Park avenue, Auckland, in

the Provincial Districtof Auckland, in'thev Dominion of New Zealand,have invented certain new and useful Improvements in Extension-Tables,of which the following is a specification.

This invention relates to tables provided with means whereby they maybeextended so as to accommodate a greater number of sitters than normallyuse the table, and the object of the invention is to provide a tablewhich is readily and instantly extended by merely operating false endswith which the table is provided.

According to this invention, false ends of a table are provided withslides which pass through the ends of the table frame and through guidesat or near the center of the table. 7

The false ends are pulled out and pushed in by simple physical forces,or mechanism is employed whereby the drawing out or pushing in of onefalse end causes the other false end correspondingly to. be pushed in orpulled'out, or mechanism is employed and operated to push in or pull outthe false ends simultaneously.

Mechanism employed when the operating of one false end operates theother false end comprises slides fixed to the false ends and providedwith racks, and a pinion or pinions gearing with the said racks. Whenone false end is operated the motion is transmitted in a reversedirection by the pinion or pinions to the other rack or racks and falseend.

In one construction, each false end has a central slide to which a rackis fixed, and slides at the sides of the table act as guides for thefalse ends.

In another construction, the central slide is dispensed with, and slidesat the sides of the table are provided with racks and pinions.

Mechanism employed to operate both false ends in opposite directionscomprises a pinion or pinions and racks, the said pinion or pinionsbeing driven by turning a handle or key.

In one construction the racks are fixed to a central slide and gear witha pinion fixed to a spindle fitted with a handle or key at one or bothsides of the table.

In another construction the central slides are dispensed with, andslides at the sides of the table are provided with racks gearing withpinions fixed to a spindle fitted with a handle or key at one or bothsides of the table.

Each extension comprises a leaf fixed to and movable with the false endand other leaves flexibly connected to the said fixed leaf. The tabletop is supported upon brackets or slide boxes fixed to the sides of theframe, and the said sides are cut away to allow the flexibly connectedleaves to pass beneath the table top when the false ends are pushedinward, and to pass from beneath when the said ends are pulled outward.

The invention may be conveniently and advantageously carried intopractice as shown in the accompanying drawings, wherein z- Figure 1, isa side elevation with the extensions not drawn out,

Fig. 2, is a side elevation with the extensions drawn out, i

Fig. 3, is a plan with the false ends drawn out and part of the tabletop and the extensions removed, this view showing both brackets 27 andboxes 27* hereinafter described,

c Fig. 4, is an end elevation of the table, showing boxes 27 but notbrackets 27,

Fig. 5, is a cross sectional elevation on line 55 Fig. 1

- Fig. 6, is a sectional elevation, and

Fig. 7, is a side elevation embodying the construction when the racksare operated by a pinion spindle and handle.

The false ends 10' and 11 are fixed to slides 12. which are supported bypassing through the ends 13 of the frame of the table,,and through a bar14 extending transversely between the sides 15 of the said frame. Broadleaves 23 are flexibly connected together by hinges, links or bands 24-,and the first of said leaves 23 is flexibly connected to a leaf 25 fixedto each false end 10 and 11. The sides 15 are cut away at the top andhave sloping ends 26. The table top 22 is supported upon brackets 27,which are fixed to the sides 15 and bow outward to extend around theends of the leaves 23 and then turn inward to support the table top,which is fixed to the said brackets.

A horizontal passageway 28 with inclined ends is thus formed between thesides 15 and'the table top 22, whereinto the broad leaves 23 may pass,moving along it in a straight line without inversion and lying fiat andhorizontal therein, parallel to the top of the table. Instead ofbrackets 27 slide boxes or casings 27 may be employed, which cover theends of the leaves 23 as well as support the table top 22.

Carriages consisting of bars connected together by a hinge 31, areconnected at their other ends to the ends 13 of the frame and to thefalse ends 10'and 11 by hinges 32. The said carriages 30 open and closeautomatically on their hinges when the false ends 10 and 11 are drawnout and pushed inward, and form supports for the leaves 23, when thesame are drawn out of the passageway 28.

' The false end 10 or the false end 11 and the leaves 23 can be pulledout or pushed in separately by simple physical force.

I The false ends 10 and 11 may be operated by providing central slides16 and 17 provided with racks 18 gearing 011 diametri+ cally oppositesides with a horizontal pinion 19, the spindle 20 of which is operableby a. key passed through a small hole 21 in the table top 22, or isoperable from below the table by a handle, key or wheel.

Again the false ends 10 and 11 may be operated by the mechanism, shownin Figs. 6 and 7 wherein a vertical pinion 35 is fixed to a spindle 36extending transversely across the frame 15 and operable by a handle 37,a key or a wheel. Racks 38 and 39 gearing on diametrically oppositesides with the pinion 35, are fixed to the slides 12 and 12 respectively, which are housed in a slide box 40. The slide 12 is reduced indepth at that part of the same whereto the rack 38 is fixed. The rack 39is fixed to a stirrup shaped bracket 41 secured to the slide 12,

' the bottom of the bracket beingextended laterally to receive the saidrack 39. A pinion 35 is provided at each side of the table when theracks are fixed to the slides 12 and 12 as described. may, however, befixed to the central slides 16 and 17, in which case they are arrangedclose together and the racks and a single pinion are arranged as shownin Figs. 6 and 7.

The legs 42 are detachably connected, so that theymay be readily removedfor the purpose of reducing space occupied by the table duringtransport. A bolt 43 project- The racks 38 and 39 ing from the end ofeach leg passes through a stretcher 44: extending transversely across,or longitudinally along, and fixed to the bottom of the frame 15. Or thesaid legs may be fixed to the stretcher by more than one bolt, or bybrackets or otherwise. Also by fixing the legs to a stretcher asdescribed, space is provided above the said legs for the passage of theslides 12 and 12.

Letters Patent of the United States is 1. An extension table havingfalse ends supported fixedly and flexibly connected broad leavesarranged in series and attached to the said ends, said table being alsoprovided in its middle part under its top with.

a horizontal passage and said leaves being arranged in shortening thetable toeenter said passageway moving in a straight line therein withoutinversion and takeposition horizontally under said table top.

2. The herein described extension table,

having false ends to which flexibly connected leaves are connected,devices fixed to the frame of the table and supporting the table top,the said devices being bowed out ward and the sides of the frame beingcut away, whereby a passageway is formed beneath the table top for theflexibly connected leaves, substantially as set forth.

3. The herein described extension table, having false ends to whichflexibly connected leaves are connected, slides connected to the falseends and provided with racks,

' What I do claim and desire to secure by.

and a horizontal pinion gearing on diametf rically opposite sides withthe racks, the spindle of the said pinion being operable by a keypassing through a hole in the table top, substantially as set forth.
